How to create OpenCore config.plist for booting macOS on AMD Desktops
An EliteMacx86 Exclusive Guide - This guide covers creation of config.plist for booting macOS on AMD Desktops for OpenCore as a bootloader.
Overview
The config.plist is a system configuration file for the Hackintosh and allows to boot macOS. Without a config.plist, no machine can boot into macOS.
A sample config.plist file is bundled with OpenCore. The config.plist which comes with OpenCore, is the default config.plist and is not optimised for all the systems. It can boot into some installation but when talking about the majority, it will fail to boot on most of the newer machines and high end builds.
Also, it's a good idea to create a config.plist for each specific system which will exclude the errors and trouble while installation and you can easily boot into macOS installation. The configuration file is written in XML and can be edited using a plist or text editor. But we don't recommend you to use a text editor as it has a chance of config.plist file corruption. The best way to edit a config.plist is to use some specific tools like Xcode, Plist Editor Pro etc..
This guide covers a creation of basic config.plist which will allow to boot your supported AMD Desktop system. To check whether your hardware is supported or not, check the compatibility table mentioned in this guide.

Notes:
It's good to have a minimal configuration and options set before you install. Once you install, you can add the other options later on. This will cause less trouble and speedup the installation process.
As it's a basic config.plist creation guide, so only important sections has been discussed. This will only allow to boot your system. For further hardware functioning, check the related guides on the forum.
All the properties and schemes must be defined. Do not delete sections unless specified in the guide or OpenCore will result in error.
This guide is as per OpenCore 0.6.3 (Release) standards.

67
Enables logging and provides more debug information.
Using this option requires Debug version of OpenCore.
Disable WatchDog
YES
Some types of firmware may not succeed in booting the operating system quickly, especially in debug mode, which results in the watchdog timer aborting the process.
This option turns off the watchdog timer.
This option also fixes Kernel Panic due to watchdog timeout.
It's recommended to set this option to "enabled."

For this option to work RequestBootVarRouting is required to be enabled.
Use of Bootstrap option will also enable "OpenCore" instead of UEFI: OS followed by your drive name in Boot Menu.
DmgLoading
Disabled
Signed
Any
Define Disk Image (DMG) loading policy used for macOS Recovery.

Disables loading of DMG images.
Disabled policy will still let macOS Recovery to load in most cases as there usually are boot.efi files compatible with Apple Secure Boot.
Manually downloaded DMG images stored in com.apple.recovery.boot directories will not load.
Signed
Enables only Apple-signed DMG images will load. Due to Apple Secure Boot design Signed policy will let any Apple-signed macOS Recovery to load regardless of Apple Secure Boot state, which may not always be desired.
It's recommended to set this option to "Signed" to avoid issues.
Any
Enables any DMG images will mount as normal filesystems.
Any policy is strongly not recommended and will cause a boot failure when Apple Secure Boot is activated.

debug=0x100
keepsyms=1
STRING
Adds boot args which provides several functions.
-v
Enables verbose mode. Helpful to track the installation progress or when booting.
We recommend to use this boot arg.

Disables PCI debugging related to kIOPCIConfiguratorPFM64.
This issue can also fix stuck on "PCI Start Configuration Begin" as there are IRQ conflicts relating to PCI lanes.
alcid=xx
Sets Layout ID for AppleALC.
The xx represents the layout ID for your codec.
agdpmod=pikera
Fixes Black Screen at boot for NAVI GPUs.
If you're using and AMD NAVI based GPU, you'll need to use this boot arg.
debug=0x100
This disables macOS's watchdog which helps prevents a reboot on a kernel panic.
keepsyms=1
This is a companion setting to debug=0x100 that tells the OS to also print the symbols on a kernel panic.
This can give some more helpful insight as to what's causing the panic itself.
nvda_drv
31
DATA
Enables NVIDIA WebDrivers.
Equivalent to Clover's NVIDIAWeb option in System Parameters.
If you're using an NVIDIA GPU, you'll need to use this key.
csr-active-config
00000000
DATA
Defines SIP type.
00000000
Enables SIP completely. (0x0)
It's advised to configure SIP via recovery using "csrutil."
If "npci=0x2000", doesn't works, use "npci=0x3000."
Do not use "npci=0x2000" with "npci=0x3000". Use only one. Never both.

The common Booter Quirks for 17 and 19h Systems includes:
Ouirks
Value
Notes
AvoidRunTimeDefrag
YES
Fixes certain UEFI runtime services such as date time, NVRAM, power control, etc.
Apart from Apple and VMware, this quirk is required by rest of the firmwares
EnableSafeModeSlide
YES
Patch bootloader to have KASLR enabled in safe mode.
This quirk requires ProvideCustomSlide to be enabled.
This quirk can be helpful if you're unable to boot into safe mode.
EnableWriteUnprotector
YES
Allows write access to UEFI runtime services code.
This quirk may potentially weaken firmware security, please use RebuildAppleMemoryMap if the firmware supports memory attributes table (MAT)
ProvideCustomSlide
YES
Provide custom KASLR slide on low memory.
This option forces macOS to use a pseudo random value among the available ones.
SetupVirtualMap
YES
Setup virtual memory at SetVirtualAddresses.
Fixes several virtual address issues and tends to fix early Kernel Panics.
The necessity of this quirk is determined by early boot failures. Currently, new firmware with memory protection support (such as OVMF) do not support this quirk.
If you're using B550, A520 or TRX40 Motherboard, you'll need to disable this quirk.
RebuildAppleMemoryMap
YES
Generates Memory Map which is compatible with macOS.
Since several types of firmware come with incorrect memory protection tables, this quirk often comes paired with SyncRuntimePermissions.
SyncRuntimePermissions
YES
Update memory permissions for runtime environment.
The need for this quirk is indicated by early boot failures. Only firmware released after 2017 is typically affected.
ProvideMaxSlide
0
Provide maximum KASLR slide when higher ones are unavailable.
Note:
The values which have been not discussed above, that will remain disabled.

67
Enables logging and provides more debug information.
Using this option requires Debug version of OpenCore.
Disable WatchDog
YES
Some types of firmware may not succeed in booting the operating system quickly, especially in debug mode, which results in the watchdog timer aborting the process.
This option turns off the watchdog timer.
This option also fixes Kernel Panic due to watchdog timeout.

It's recommended to set this option to "Signed" to avoid issues.
Any
Enables any DMG images will mount as normal filesystems.
Any policy is strongly not recommended and will cause a boot failure when Apple Secure Boot is activated.
